Dave:

Current should hold it open. Probably need to hook up the ammeter and see what kind of current you have. I think I remember that 600 mA is wide open.

Could just be a bad idle control valve, but they are expensive enough that I wouldn't buy one just to check.

Try tapping the OVP, too -- if it's bad, that may correct the idle temporarily, it can switch the idle circuit funny if the relay is bad and only making partial contact.

The only problem you might have is stalling if the AC compressor comes on at idle.

I just did the water pump on the TE this fall -- took me 6 hours and with new visco clutch and tensioner, ran about $600 in parts.

I've got three 6-gallon batches of beer going, will probably do another one next weekend since I can only make lagers this time of year.
